What Is This Charge?
The descriptor 'PURCHASE KOS - BOOSTER' likely refers to a transaction with a merchant related to wellness or fitness products, possibly a health supplement or energy booster product. The 'KOS' may indicate a brand name or product line, while 'BOOSTER' suggests a focus on enhancing physical performance or energy levels.
Why You May Not Recognize This Charge
This charge may not be recognized due to the use of an abbreviated merchant name (KOS) and the word 'BOOSTER,' which can be common in health-related products but lacks specific identification. Customers might also be unfamiliar with the brand or product if they did not purchase it directly or if it was a subscription that they forgot about.
When Should You Be Concerned?
Consider reaching out to your bank or card issuer if you don't recognize this charge, didn't authorize it, or see it appear multiple times without explanation. We don't determine whether a charge is fraudulent — only your bank or the merchant can do that.
What to Do Next
- Check your recent purchases and receipts to see if the charge matches anything you bought.
- Contact your bank or credit card company if you don't recognize the charge — they can help verify it or dispute it.
- Monitor your account for any additional unusual activity.
